The 20,000 to 60,000 didn't show for the Wieser, ID festival. Vendors had to settle for about 1200. No traffic jam, just an average day. Looks like central Oregon was the only traffic kaos I heard about.

All the campgrounds along I 84 were sold out, but they would be sold out or close to it on any August weekend
